how can I fix my MTX-8 hand controllers display? It worked ok last week and all of a sudden it doesnt show any thing but the light. It is directly to the unit cause I need to lower the idle and tried the throttle cable and still nothing. I cant get my laptop to even recognize it, and I have the software to it loaded. My Tech, oil pressure and water temp wont read on the stock cluster so I'm running of my 10grand 5" tach. The idle is at 2800 rpm and I'm not trying to get rolled up because of my car is super loud and the stock turbo is spooling loud!!!

 

Water temp gauge goes to hot whit the ignition on but not running how do I lower my Idle any help would help!!!

 

no display on the hanset is most likely to be an issue with the coms cable or electrical noise from the ignition and likely both


change out the coms cable for a new one

 

I put the handset directly to the ecu by removing one of the locking screw things on each one ecu and hand set and they worked before trailing my car home. and stopped the day I got it home, thats how I had found out my TPS needed to be calibrated! I dont have the Dongle so I guess it wont connect to the ecu is what I finally found on the site. But with the lt65 software it recognizes it under com port 5 but wont let me do anything. It's to late to start the car so I'm stuck cause the idle is so high!!!
